Answer: The area of a triangle is 1036.8 square units.

To find the area of a triangle, we can use the formula

Area = (1/2) * base * height

In this case, we are given that the first base is 32 and the second base is twice the first base, or 2*32 = 64. The height is given as 21.6. Therefore, we can plug these values into the formula and solve for the area:

Area = (1/2) * (32 + 64) * 21.6

Area = (1/2) * 96 * 21.6

Area = 1036.8

Therefore, the area of the triangle is 1036.8 square units.

The measurement of three-dimensional space is volume.

It is typically quantified using a variety of imperial or US-standard units as well as SI-derived units.

The concept of length and volume are related.

Volume is the three-dimensional space inhabited by matter or encompassed by a surface, and it is measured in cubic units.

The SI unit of volume is the cubic meter (m³), which is a derived unit.

So, the volume would be:

length x breadth x height

Step 1 : substitute the values given

Step 2 : 10 x 4 x 6

Then, we got: 240 inches

The exponentially smoothed forecast for period 4 is 106.6.

As per given information,

Time period Actual series  Forecast series  Forecast error  1  100  100 0 2 110 3 115

Smoothing constant α=0.3

For calculating exponentially smoothed forecast for period 4,

First, we need to calculate exponentially smoothed forecast for period 2.

Smoothed forecast for period 2 = α (Actual demand for period 1) + (1-α) (Smoothed forecast for period 1)

= 0.3 (100) + (0.7) (100)= 30 + 70= 100

Next, we can calculate exponentially smoothed forecast for period 3.

Smoothed forecast for period 3 = α (Actual demand for period 2) + (1-α) (Smoothed forecast for period 2)

= 0.3 (110) + (0.7) (100)

= 33 + 70

= 103

Now, we can calculate exponentially smoothed forecast for period 4.

Smoothed forecast for period 4 = α (Actual demand for period 3) + (1-α) (Smoothed forecast for period 3)

= 0.3 (115) + (0.7) (103)= 34.5 + 72.1

= 106.6

Martin will have to wash 96 cars each month on average to meet his goal of washing 1,200 cars this year.

What is average ?

Average, also known as mean, is a statistical measure that represents the central value of a dataset. It is calculated by adding up all the values in the dataset and dividing by the total number of values. The average can be used to provide a general idea of the value of the dataset and to compare different datasets. There are different types of averages, including arithmetic mean, geometric mean, and median.

According to the question:
To find out how many cars Martin will have to wash each month on average, we need to first find out how many weeks there are in a year:

52 weeks/year

Then we can use this information to calculate how many cars Martin will have to wash each week:

1,200 cars/year ÷ 52 weeks/year = 23.08 cars/week

Since Martin cannot wash a fraction of a car, he will have to round up to 24 cars/week.

Finally, we can calculate how many cars Martin will have to wash each month on average:

24 cars/week x 4 weeks/month = 96 cars/month

Therefore, Martin will have to wash 96 cars each month on average to meet his goal of washing 1,200 cars this year.

The probability of 4 defective cell phones in a sample of 25 can be found using the binomial probability formula and is equal to 0.0263.

Probability is a branch of mathematics that deals with calculating the likelihood of a given event occurring. In probability, we calculate the number of ways an event can happen and divide it by the total number of possible outcomes.

Probability ranges from 0 to 1, with 0 indicating no chance of occurrence and 1 indicating that the event will definitely occur.

If there are only two possible outcomes in a given event, the binomial probability formula is used to calculate the probability of the event happening.

The binomial probability formula is given by: P(X = x) = (nCx)px(1 - p)n - x

Where, P(X = x) is the probability of x successes in n trials

nCx is the number of ways x successes can occur in n trials

px is the probability of a single success in a given trial(1 - p)n - x is the probability of the remaining trials being failures.

The coordinate of the point U that divides the line ST in the ratio 2:5 is: (12:6)

The formula for the division of line segments in the ratio m:n is

P = {[(mx2 + nx1)/(m + n)], [(my2 + ny1)/(m + n)]}

We are given the coordinates of line Segment ST as: S(10, 2) and T(17, 16)

Thus, if the ratio is 2:5, we have:

U(x, y) = {[(2*17 + 5*10)/(2 + 5)], [(2*16 + 5*2)/(2 + 5)]}

U(x, y) = (84/7), (42/7)

The sum of the circumscribed angle m∠ECD and central angle m∠EAD for five different data sets are 90°, 90°,120°,150°,180°.

A central angle is an angle in a circle that has its vertex at the center of the circle. Its arms, which are the two rays that make up the angle, both pass through points on the circumference of the circle.

m∠ECD  m∠EAD  m∠ECD + m∠EAD

100°  20°    120°

140°  10°    150°

180°  0°    180°

The measure of the circumscribed angle, ∠ECD, is the angle formed by the intersection of two lines, AB and CD.

The measure of the central angle, ∠EAD, is the angle formed by the intersection of the lines AB and ED.

The relationship between the circumscribed angle and the central angle can be explored by moving point B to various different locations on the coordinate plane between A and C.

By doing so, both the circumscribed angle and the central angle can be measured.

From the table above, it can be seen that the sum of the measures of the circumscribed angle and the central angle is always equal to 90°.

This is because the circumscribed angle and the central angle are supplementary angles, meaning that the sum of their measures always equal to 180°.

In this case, since the sum of the measures of the circumscribed angle and the central angle is always equal to 90°, the measures of the circumscribed angle and the central angle themselves must always add up to 90°.

Answer:

x = 17/4, or 4.25

The x-intercept is (4.25, 0)

Step-by-step explanation:

We can get the intercepts by isolating x and y.

4x - 3y = 17

Subtract 4x from both sides.

-3y = -4x + 17

Divide both sides by -3.

y = 4/3x - 17/3

Input 0 for x.

y = -17/3

The y-intercept is (0, -17/3)

4x - 3y = 17

Add 3y to both sides.

4x = 3y + 17

Divide both sides by 4.

x = 3/4y + 17/4

Input 0 for y.

The value of ∠FDE is 36°

An angle is a geometric figure formed by two rays, or lines that extend infinitely in opposite directions, that share a common endpoint called the vertex. The measure of an angle is determined by the amount of rotation between the two rays.

Here given a right angle ∠CDE = 90°

So, we can say that,

∠CDF + ∠FDE = ∠CDE

(2x)° + (x+9)° = 90°

(3x + 9)° = 90°

Simplify it, x = 27°

So, the value of ∠FDE = (x+9)° = (27+9)° = 36°

The solutions to the trigonometric equations [tex]2cos(x) - \sqrt{30} = 0[/tex] in the interval [tex][0, 2\pi)[/tex] are x ≈ [tex]0.5514 + 2n\pi[/tex], where n is an integer.

Given that the equation  [tex]2cos(x) - \sqrt{30} = 0[/tex] in the interval [tex][0, 2\pi)[/tex]

To find all the solutions to the equation  [tex]2cos(x) - \sqrt{30} = 0[/tex] in the interval [tex][0, 2\pi)[/tex] ,  solve for x by isolating the cosine term and then applying the inverse cosine function.

Here are the steps to solve the equation:

Add [tex]\sqrt{30}[/tex] to both sides:

[tex]2cos(x) = \sqrt{30}[/tex]

Divide both sides by 2:

[tex]cos(x) = \sqrt{30} / 2[/tex]

Find the inverse cosine ([tex]cos^{-1}[/tex]) of both sides:

[tex]x = cos^{-1}(\sqrt{30} / 2)[/tex]

To determine the values of x in the interval [tex][0, 2\pi)[/tex] that satisfy the equation.

Evaluate [tex]cos^{-1}(\sqrt{30} / 2)[/tex] to find its approximate value.

[tex]cos^{-1}(\sqrt{30} / 2) = 0.5514[/tex] radians

Since the cosine function has a periodicity of [tex]2\pi[/tex], we can find other solutions by adding multiples of [tex]2\pi[/tex] to the initial solution.

So, the solutions in the interval  [tex][0, 2\pi)[/tex] are:

x ≈ 0.5514 radians

x ≈ [tex]0.5514 + 2\pi[/tex]

x ≈ [tex]0.5514 + 4\pi[/tex]

...

To simplify, express the solutions as:

x ≈ [tex]0.5514 + 2n\pi[/tex]

where n is an integer.

Therefore, the solutions to the trigonometric equations [tex]2cos(x) - \sqrt{30} = 0[/tex] in the interval [tex][0, 2\pi)[/tex] are x ≈ [tex]0.5514 + 2n\pi[/tex], where n is an integer.
